5.5.3 On-Emulator Break

• A break will occur several cycles after a condition is satisfied.

• The address bus and data bus conditions are satisfied on the bus cycles where the values on the address bus

or data bus match. Consider the following points when setting these conditions.

⎯ 32-bit bus area

• Longword access

Longword data is read and written in a single bus cycle. A data condition is only valid for a longword

access when specified as longword. An address condition is only valid for a longword access when

specified as a multiple of four.

• Word access

Word data is read and written in a single bus cycle. A data condition is only valid for a word access

when specified as word. An address condition is only valid for a word access when specified as a

multiple of two.

• Byte access

Byte data is read and written in a single bus cycle. A data condition is only valid for a byte access

when specified as byte. Any address condition, whether an even or odd address, is valid.

⎯ 16-bit bus area

• Longword access

Longword data is read and written in two bus cycles. A data condition is only valid for a longword

access when specified as word. An address condition is only valid for a longword access when

specified as a multiple of two.

• Word access

Word data is read and written in a single bus cycle. A data condition is only valid for a word access

when specified as word. Any multiple of two is a valid address condition.

• Byte access

Byte data is read and written in a single bus cycle. A data condition is only valid for a byte access

when specified as byte. Any address condition, whether an even or odd address, is valid.

⎯ 8-bit bus area

All accesses are done in bytes in this area (a longword is accessed in four byte cycles, and a word in two

byte cycles). Any address condition, whether an even or odd address, is valid. A data condition is only

valid when specified as byte.
